Dry eye disease signs and symptoms are highly heterogeneous. In some Far Eastern countries, the prevalence of dry eye is reported in the younger population ( under 25 years of age ) as compared to the older population in the rest of the world. The trend for this may be related to risk factors such as myopia, use of mobile phones and computers, and prolonged video-based teaching time as well as video games for entertainment.
For easy use and convenience of the younger population, a recently introduced nasal spray containing the molecule nicotinic acetylcholine receptor agonist has been introduced. The novel method, via a multi-dose preservative-free nasal spray, spares the ocular surface and represents an effective way to manage dry eyes. Study results are yet to be published shortly.
